We look at the division of 74857779 by 991 
We want to divide 74857779 by 991.

Let's proceed to step 1:
7 divided by 991 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 991

Going ahead to step 2:
The number 991 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 991

Going ahead to step 3:
991 can be fit into 748 0 times, resulting in a remainder of 748.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 748, we end up with 748.
Take the next digit (5) from the dividend and append it to 748, then repeat: 7485 / 991

Let's proceed to step 4:
7485 divided by 991 is 7 with a remainder of 548.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6937 from 7485, we get 548.
Grab the next digit (7) from the dividend, add it to 548, then carry on: 5487 / 991

Let's proceed to step 5:
5487 divided by 991 is 5 with a remainder of 532.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 4955 from 5487 leaves us with 532.
Append the next digit (7) from the dividend to 532 and continue with: 5327 / 991

Moving on to step 6:
5327 divided by 991 is 5 with a remainder of 372.
Put 5 as the next digit of the answer. 
Result so far: 755.0
If we take 4955 away from 5327, we end up with 372.
Include the next digit (7) from the dividend after 372, then repeat: 3727 / 991

Step 7:
If we divide 3727 by 991, we get 3 and a remainder of 754.
Put 3 as the next digit of the answer. 
Result so far: 7553.0
Subtract 2973 from 3727 to get 754.
Take the next digit (9) from the dividend and append it to 754, then repeat: 7549 / 991

Advancing to step 8:
When dividing 7549 by 991, we get 7 with a remainder of 612.
Put 7 as the next digit of the answer. 
Result so far: 75537.0
If we subtract 6937 from 7549, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 9:
If we divide 6120 by 991, we get 6 and a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 75537.6
Subtract 5946 from 6120 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 10:
When dividing 1740 by 991, we get 1 with a remainder of 749.
The next digit of our result is 1. 
Result so far: 75537.61
Deduct 991 from 1740 and we're left with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Advancing to step 11:
If we divide 7490 by 991, we get 7 and a remainder of 553.
Use 7 as the next digit of our solution. 
Result so far: 75537.617
Subtract 6937 from 7490 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 12:
The number 991 fits into 5530 5 times, leaving a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 75537.6175
If we subtract 4955 from 5530, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 13:
If we divide 5750 by 991, we get 5 and a remainder of 795.
The number 5 becomes the next digit in our result. 
Result so far: 75537.61755
Deduct 4955 from 5750 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

In conclusion, the division gives 75537.61755 with a balance of 0.000795.
